To all whom it may concern:

Be itknown that I, DUNCAN GRAY, of the town of Alexandria, in the countyof Glengarry, Province of Ontario, Dominion of Canada, have invented certain new'and useful Improvements in Whey-Measuring Apparatus, of which the following is a specification. 1

My invention relates to whey measuring apparatus. 1

The object of my invention is to provide an apparatus by means of which agiven quantity ofv whey, or other liquidymay be run off from a tank, and. when that quantity has been run off, the supply will be'automatically stgppgd.

rther object issto provide an apparatus of the character described, which may be operated from the office, or other point removed from the vat containingthe whey.

.My invention consists of the construction, combination and arrangement of parts, as herein illustrated, described and claimed.

In the accompanying drawings, forming part of this a plication, I have illustrated one form of em odiment -of my invention, in which drawings similar referencecharacters designate corresponding Iparts, and in which:

Figure 1 is a vertica section through a whey vat and connected parts; Fig. 2 is a plan view of the whey vat and connected parts; Fig- 3 is a vertical section through a closure or valve; Fig. 4 is an inverted plan view of a closure or valve; Fig. 5 is a fragmentary detail in horizontal section through a locking pawl; and, Fig. 6is a fragmentary portion of a lockin rack.

lieferring to the drawings, 1 designates a supporting member, on which is disposed a whey vat 2. A discharge pipe 3 has one end connected with the interiorof the vat 2, and has its opposite end connected with an en ended tank 4, which 'is'provided with a cischarge faucet 5. To prevent use of the apparatus until desired, a globe valve 40 is pr o-. vided located within a casing 41, the cover'42 of which may be locked in position. The discharge pipe Sand the faucet are each provided with atubular closure 6, having a projecting flange 7 formed to receive a gasket 8 on its under face, so that a perfect closure is made bythe weight of the whey pressing on the flange 7. a

. A rod or connecting member 9 has its lower end connected to the closure 6 for the outlet pipe 3, and has the opposite end secured to the long end of a lever 10, which is pivotedas at 11, and has secured to itsopposite end a flexible connecting member 12, to the lower end of-the latter of which is secured the closure 6for the faucet 5. The lever 10 is so pivoted that-its inner end will normally close the closure 6 connectedtherewith, and the connecting members 9 and 12 are roportioned in length so that the pipe 3 amffaucet 5 will be alternately closed. a

- Movably disposed in the tank 4 is a float 13, provided with an opening for the connecting member 12, so that the float is free to move vertically in the tank.

Loosely disposed through the outer end of the lever 10 isa rack 15, adapted to be engaged by a pawl 16, secured on a stem 17 and normally maintained in the path of movement. of the rack as by means of a s ring 18. The stem 17- is disposed throug an opening 19 in the block 20, which is adjustably securedin the side members21 forming the lever 10. When in the position shown in Fig. 1, the pawl 16 engages the rack so as to causedownward movement of the outer end of the lever. This opens the closure for the outlet pipe 3, and permits the whey to run into the tank 4. Loosely disposedthrough the lever 10, is a casing 22 engaging the rack 15, and connected therewith by means of transverse pins 23 passing through diagonal slots 24 in the rack, thus holding the rack so that it may be retracted into the casing 22 to release the lever and permit its inner end to descend and seat the closure 6 in the to of the outlet pipe 3. This retraction of tl e rack into the casing is caused by the float 13 rising under the action of the whey admitted to the tank 4 below the float. The faucet 5 being open, the whey will be drawn ofl from the tank 4, the float will descend gradually, and finally the rack will be released and will be again engaged by the pawl 16 when the casing is elevated, as hereina'fter described. r

A flexible member 25 has its lower end secured to the casing 22, and is disposed over a roller 26 carried by an arm 27 secured to the vat 2, and also serving as a pivotal sup port for the lever 10. The flexible member is then disposed over rollers 28, and around a winding member 29, which may be finally located in theoflice of the plant to which this apparatus is connected. A scale 30 is secured to the flexible member 25, and disposed in guides 31 adjacent pointers 32, which will indicate in figuresthe height to which the casing is drawn, and the proportion of whey which will be admitted to the tank 4 when the rack 15 is elevated to any particular point. As above described, when this quantity of whey is admitted, the lever will be tripped, the closure will be seated on the outlet pipe 3, and when the whey has been run off from the tank 4 the apparatus may be reset.

In the operation of the invention, the in ner end of the lever 10 being lowered and the float 13 being adjacent the bottom of the tank 4, and it being desired to deliver a predetermined quantity of whey from the va-t 2, the winding member 29 is actuated to move the flexible member 25, so that the casing 22 and the rack 15 are actuated upward until the scale 30 indicates such quantity. On its upward movement the rack 15 isfree to slide over the pawl 15. The quantity being ascertained by means of the scale 30, the teeth of the rack 15 engage the pawl and the weight of the rack causes the lever 10 to be rocked on its pivotal support, ele-- vating the closure 6 from. the end of the outlet pipe 3, permitting the whey to run through the pipe 3 into the tank 4', and car rying with it the float 13, which is elevated until ,it strikes the bottom of the rack 15. The float then actuates the rack upward, and the inclined slots through which are disposed the pins 23 permit the rack 15 to be actuated upward and backward into the easing 22, so that the pawl'16 is released from the teeth of therack, and the lever 10 is permitted to rock by its own weight on its pivotal support 11, and the closure 6 seats itself on the end of the pipe 3, thereby cutting oit the supply of whey. The faucet 5' is opened by the closure 6 being elevated therefrom by the flexible member 12, which is connected to the outer end of the lever 10, and the quantity of whey in the tank 4 is permitted to run ofl, the rack 15 following the downward movement of the float 13. Then if a different quantity of whey is desired, the winding member is actuated for such different quantity.
